Ko te papu-whaiaro he papu centrifugal-whaiaro, he pai nga painga o te hanganga kiato, he watea te mahi, he pai te mahi, he ngawari te tiaki, he tino pai, he roa te ora, me te kaha o te kaha ki te whakakii.Kaore he take ki te whakauru i te riipene o raro i roto i te paipa, me whakarite noa he wero wai ine i roto i te tinana papu i mua i te mahi.Ka taea e nga wai rereke te whakamahi i nga rauemi rereke o te papu whakamaarama whaiaro.
Mena kei raro te taumata wai momi i raro i te impeller, me whakakiia ki te wai i te wa e tiimata ana, he tino koretake.Hei pupuri i te wai ki roto i te papu, me whakauru he takirere o raro ki te kokoru o te paipa momi.I te wa e mahi ana te papu, ka nui te mate o te waipēhi o raro.Ko te mea e kiia nei ko te papu-whaiaro e kore e hiahiatia kia whakamakuku i mua i te tiimata (ko te tiimata tuatahi i muri i te whakaurunga me whakamakuku tonu).I muri i te wa poto o te mahi, ka taea e te papu tonu te ngote i te wai ka tuu ki te mahi noa.
